Product information "SPI Isolator click"

SPI Isolator click carries the ADuM4154 5kV digital isolator optimized for a serial peripheral interface (SPI). The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over SPI interface.

ADuM4154 features

The ADuM4154 has four high-speed channels. The first three channels, CLK, MI/SO, and MO/SI (the slash indicates the connection of the particular input and output channel across the isolator) are optimized for either low propagation delay in the B grade, or high noise immunity in the A grade.

Note: For more information about the A and B grade specifications see the datasheet.

Take a look at how the click can be connected in the picture below:

Note: For this example we used the ccRF 3 click and the EasyPIC v7 development board

SPI communication

SPI (Serial Peripheral Interface) communication is one of the most popularprotocols for sending data between microcontrollers and different peripherals.

It is a synchronous protocol; the clock signal is provided by the master.
